Team-blacksheep have very nice frame for DJI-NAZA with some fancy PDB, but I don't have NAZA and I wanted some modification to mount APM2/2.5, so here is my version of that frame, no fancy PDB and PCBs, just black fiberglass :)
If you do have DJI NAZA go get that frame right NOW !
APM2.0 with 90° pins fits under the top plate with analog and telemetry pins exposed.
APM2.5 with ublox GPS.
Set the LED_MODE parameter to 9, It will slow blink when disarmed, solid armed, fast blink + beep on low battery.
The CG and the APM location moved a little bit, but it can fly as regular X quad. (don't pull back too much)
I just changed the AP_MotorsQuad.cpp X frame set-up to:
add_motor(AP_MOTORS_MOT_1, 55, AP_MOTORS_MATRIX_MOTOR_CCW, AP_MOTORS_MOT_2, 1);
add_motor(AP_MOTORS_MOT_2, -125, AP_MOTORS_MATRIX_MOTOR_CCW, AP_MOTORS_MOT_1, 3);
add_motor(AP_MOTORS_MOT_3, -55, AP_MOTORS_MATRIX_MOTOR_CW, AP_MOTORS_MOT_4, 4);
add_motor(AP_MOTORS_MOT_4, 125, AP_MOTORS_MATRIX_MOTOR_CW, AP_MOTORS_MOT_3, 2);
Setup
Motors: Tiger MS2212-13 980KV
ESC: jDrones 18A (Flashed with SimonK FW)
I really like the 10X5 Graupner e-props (or new Carbon 10X5 e-props) with 4S 3000mah lipo, after some fine-tuning its very sharp fly.
Here some raw clips from Arducopter 2.8.1 tuning flights:
BTW Jani from jDrones (that where I CNC all my custom frames ;) ) has put together fancy RTF kit, so check that one out.
EDIT:
The top outside hols for the arms are ~0.5mm off, I think so chek it before cuting.

Interesting, thanks for sharing. It looks yours has slightly narrower angles and yet you get no props in gopros frame. Are you using the gopros narrow or wide setting ?
Nice work Max.
Once you've tuned it, would you mind sharing your param file?
Thx
@Crasher I added the DXF.
@Isaac jDrones should have them in stock soon.
@Dmitry I really like the Tilt mount that you made, I'll try it on my next build :)
Thanks for the ULN2803 wiring info
I'd love to get the DXF files for this if you ever decide to open source it! I have the TBS Discovery, but would like to experiment with a symmetrical version as while it flies good, the assymetric layout has it's limitations performance wise.
Would never give my hard earned cash to TBS
Nice work - everything done very good! But I would say it is not necessary to make a hole in the top plate to make GPS works. From my experience fiberglass not a obstacle for this sensor. My copter have 2 GPS - AMP2.0 and Eagletree inside http://diydrones.com/photo/dsc05074 and http://diydrones.com/photo/my-new-project-flow working good!
Nice job. I've been using the graupners on here with a 4S 6000mah and it still fly's really great. I just have the f450 normal frame though. What are the carbon props you were referring too?
